Broccoli Seed Extract Sulforaphane 10% for Dietary Supplements
product description
Sulforaphane is an isothiocyanate formed when the plant enzyme myrosinase hydrolyzes glucoraphanin, a glucosinolate concentrated in broccoli seeds. Because sulforaphane itself is chemically unstable, the practical bulk form for supplement manufacturing is broccoli seed extract standardized for glucoraphanin and supplied with active myrosinase enzyme.
KH Health produces this sulforaphane ingredient from cultivated Brassica oleracea italica seed, using controlled low-temperature processing that protects both the glucoraphanin precursor and the heat-sensitive myrosinase enzyme. Each batch is standardized to a glucoraphanin assay by HPLC, with myrosinase activity quantified and reported on the certificate of analysis — so your finished capsule, tablet, or powder formula can deliver a reproducible sulforaphane yield, batch after batch.
product strength
Complete Enzyme System
Our myrosinase-active grade delivers both the glucoraphanin precursor and the enzyme needed to convert it, so sulforaphane—the bioactive isothiocyanate—forms reliably at the point of use instead of depending on variable gut conversion.
Verified Precursor & Activity
The sulforaphane precursor is assayed by HPLC, and myrosinase activity is quantified per batch—both reported on the COA for documentable finished-product consistency and reproducible sulforaphane yield.
Cellular Defense Positioning
Sulforaphane, the end-product of the glucoraphanin–myrosinase reaction, is among the most studied natural activators of the Nrf2 pathway, giving brands a science-backed angle for cellular defense, antioxidant, and detox-support lines.
Format-Flexible Powder
Fine, free-flowing powder blends cleanly into capsules, coated tablets, stick sachets, and drink mixes, with formulation guidance on avoiding heat and moisture during processing.
Product Benefits
1. Nrf2 Pathway Activation & Cellular Defense
Sulforaphane activates the Nrf2 transcription factor, upregulating phase II detoxification enzymes such as NQO1, glutathione S-transferase, and heme oxygenase-1 — a core mechanism behind its antioxidant and detox-support effects.
2. Antioxidant Support
Intervention studies report reduced oxidative-stress markers (e.g., plasma MDA and oxidized LDL) in participants consuming broccoli-sprout-derived sulforaphane.
3. Anti-Inflammatory Support
A 70-day study in overweight adults found significant declines in IL-6 and C-reactive protein with daily fresh broccoli sprout intake.
4. Metabolic Health Support
Randomized trials in type 2 diabetes patients reported improved fasting glucose and HbA1c with broccoli sprout extract (~150 µmol sulforaphane/day); a 12-week prediabetes trial showed a 0.2 mmol/L reduction in fasting blood glucose overall and 0.4 mmol/L in a defined responder subgroup.
5. Neuroprotection & Cognitive Support
A randomized 18-week trial in young men with autism showed significant improvements in behavior ratings; a study in healthy adults aged 60–80 found improved processing speed and working memory versus placebo.
6. Environmental Toxin Elimination Support
Trials in a Chinese cohort exposed to air pollution demonstrated enhanced urinary excretion of benzene and acrolein conjugates with sulforaphane-rich broccoli sprout beverages.
7. Gastric & Antimicrobial Research
Clinical studies report reduced *H. pylori*-associated gastritis markers, and in vitro data show broad-spectrum antimicrobial activity.
8. Skin Protection Research
Topical sulforaphane-rich extract reduced ultraviolet-induced erythema and DNA damage in a randomized controlled trial.
Product Application
Cellular Defense & Detox-Support Supplements
Consumers are looking for ingredients that support the body's own defense systems against everyday oxidative stress, and Nrf2-activating botanicals are a fast-growing research-backed category.
The combination of glucoraphanin precursor (≥10%) with active myrosinase enzyme ensures reliable conversion to sulforaphane—the Nrf2-activating isothiocyanate—at the point of use.
Antioxidant & Healthy-Aging Formulas
Healthy-aging brands increasingly combine phase-two enzyme inducers with classic antioxidants such as vitamins C and E and green tea polyphenols.
Broccoli seed extract blends well in capsule and tablet matrices; the mild mustard note is easily masked in coated tablets and flavored powders. The myrosinase-active grade ensures sulforaphane generation in vivo for maximum bioactivity.
Sports Nutrition & Recovery Powders
Athletes use antioxidant and anti-inflammatory ingredients to complement training recovery, and clean-label botanical actives are displacing synthetic compounds in the category.
The fine powder disperses in RTD and stick-pack sports drinks; enzyme-active grade is recommended for formats that avoid high-temperature processing, preserving both glucoraphanin precursor and myrosinase activity for optimal sulforaphane yield.
case study
Confidential — North American Supplement Brand
A North American supplement brand developing a cellular-defense capsule line switched from a non-standardized broccoli powder to our glucoraphanin ≥10% myrosinase-active grade after comparing COA data from three sulforaphane suppliers. The defined precursor basis and verified enzyme activity gave them confidence in reproducible sulforaphane generation, while the fine powder performed well in high-speed encapsulation.

FAQ
Q:What is the difference between sulforaphane and glucoraphanin?
A:Glucoraphanin (CAS 21414-41-5) is the stable glucosinolate precursor found in broccoli seeds. When it comes into contact with the enzyme myrosinase (from horseradish, mustard, or the gut microbiota), it is hydrolyzed to form sulforaphane (CAS 4478-93-7), the bioactive isothiocyanate. Our 10% grade is standardized to pre-formed sulforaphane.
Q: Is the 10% sulforaphane pre-formed or generated by activation?
A:For our Sulforaphane 10% grade, sulforaphane is quantified by HPLC after a defined activation step. We can clarify the exact assay protocol, activation conditions, and myrosinase source in the technical dossier — please ask for our batch-specific methodology.
Q:Why is myrosinase important in formulation?
A:Without active myrosinase, glucoraphanin converts to sulforaphane inefficiently, especially if the enzyme is destroyed during capsule manufacturing. Many brands co-formulate with horseradish/mustard powder or use activated extracts. We offer both activated sulforaphane and glucoraphanin + myrosinase options.
Q:Is sulforaphane water-soluble and stable?
A:Free sulforaphane is moderately water-soluble but degrades in liquid form. For beverages, we recommend stabilized formats (e.g., cyclodextrin encapsulation or water-dispersible glucoraphanin grades). Dry powder should be stored sealed, cool, and away from light and heat; shelf life is 24 months.
Q: Can I get a COA and third-party test report?
A:Yes. Every shipment includes a batch-specific COA with full heavy-metal and microbiological results. Third-party testing (SGS, Eurofins, etc.) can be arranged and is recommended for new supplier qualification.
Q: What is the lead time and shipping?
A: Stock items ship within 2–3 working days. We ship worldwide via international express (DHL/FedEx/UPS), air freight, and sea freight, with DDP/DAP service to major markets.
Q:Can you make private-label capsules or finished products?
A:Yes. We offer OEM/ODM services for capsules, tablets, sachets, and gummies, including blend formulation, packaging design, and regulatory documentation support.
Q:Is this product intended for direct consumer sale?
A:No. This is a bulk B2B ingredient for use in dietary supplements, foods, cosmetics, and research. Finished-product labeling and claims must comply with the regulations of your target market.
